Białynicki-Birula decompositions of smooth complete Gm-varieties with finite fixed loci are filterable or stratifications under conditions invariant under action reversal; for toric varieties the paper classifies when they must or may be stratifications, and filterable cell closures are determined

Structural properties of Bia{\l}ynicki-Birula decompositions
Białynicki-Birula decompositions of smooth complete Gm-varieties with finite fixed loci are filterable or stratifications under conditions invariant under action reversal; for toric varieties the paper classifies when they must or may be stratifications, and filterable cell closures are determined
